TAKE-UP ROLLdBEARING FOR LCOMS.

Application filed "February 2, 1925. Serial No. 6 ,201,

This invention relates'to the bearings for V the take-up roll of a =looin an'd the-objectof the invent-ion is :to provide a simple and efficient construction which will prevent lubricant applied to these hearings from reaching the surface "of the take u-p' roll and injuring the cloth passing thereover or from reaching the surface of the cloth roll, mounted beneath the takeup*-roll,';and injuring the cloth wound thereon. i

It is of great importance that the cloth being woven in a loom shall be kept from contamination by oil' or other lubricant employed because the cloth, if not seriously damaged thereby, requires extensive and laborious treatment for its removal. Great .difliculty has been experienced by reason of the lubricant employed on the take-up roll bearings finding its way over the end of the take-up roll onto the surface of the roll and then reaching the cloth on the take-up roll or dropping upon or being carried by the cloth upon the usual cloth roll, or the cloth wound upon the cloth roll directly beneath the take-up roll. The present invention provides a simple and efficient means for obviating this difficulty.

The nature and object of the invention will appear more fully from the accompany-- ing description and drawing and will be p-articularly pointed out in the claim.

. Fig. 1 with the loom frame shown As the present invention is concerned only with a singlefeature of construction in the looms, it is only necessary to illustrate and describe that portion of the loom directly concerned with the present invention, and

as the construction is practically the same at both sides of the 100m, it will be suflicient to describe the construction at but one side. 3 In the drawings:

Fig. 1 is a front elevation of a portion of a loom frame and adjacent ends of the take up and cloth rolls, the frame being partially broken away. 7

Fig. 2 is a view looking toward thelleft of cal cross section.

Fig. 3 is a detail of the, bearing bracket shown in Fig. 2 in vertical cross section.

In the construction illustrated,.the breast beam 1 of the loom has mounted therein at the front of the loom the usual take-up roll 2, having fast thereon at its end the usual ear 3. The cloth passes from the fell around the take-up roll.

in verti- Directly beneath the take-up roll is anounted :thensualcloth roll l. upon which the cloth is wound, It is found that lubrn its way onto the cloth roll or onto the cloth on 'the cloth roll'directly beneath, andconsequently does much damage.

In the present inventioincbearing brackets are provided at each side of the loom to receive the journals of the take-up roll, and

these bearing brackets are so constructed as to prevent lubricant passing onto the-takeup roll and as to drain surplus lubricant to a point where it will drop off without finding its way either to the take-up roll or to the cloth roll. A preferred form of one of these bearing brackets is illustrated. Such a bearing bracket is shown as comprising a flange 5, by means of which the bracket is bolted at 6 to the front of the breast beam, and another flange 7 fitting up snugly against the end surface of the breast beam.

This bracket has a rearwardly projecting arm 8 in which is formed a seat 9 for a guide roll, usually employed to guide the cloth around the take-up roll.

This bearing bracket is formed with a generally cylindrical portion 10, presenting a cylindrical bore 11 which fits the journal of the take-up roll. The upper surface of the cylindrical portion 10 is provided with a shallow recess 12 into which lubricant is fed through an oil opening 18 in the breast beamand from which it passes through an opening 14 into the bore 11, and thus to the journal of the take-up roll.

At the end of the bore adjacent the takeup roll, the bearing bracket is provided with an annular recess 15 opening throughout its inner periphery into the bore 11.

A drainage channel or groove 16 is formed at the bottom of the bore and extends along from the annular recess 15 to the opposite end of the bore, or to a position which it will be seen is wayto one side of the ends of the take-up and cloth rolls.

The construction is such that any lubricant which is supplied, as through the opening let to the take-up roll journal, if in excess of that required to lubricate the jouronto the r nal, will be caught by the annular recess 15 and led back through the drainage channel 16 and drop out of the end of this drainage channel in an innocuous position, or one Where it will do not injury to the cloth.

Having thus described the invention what is claimed as new and desired to be secured by Letters Patent, is

Lubricating bearing mechanisms for the journals of the take-up roll of a loom, having a frame including a breast beam having a vertical oil opening at each end, a cloth roll mounted in the frame to receive the cloth as it is woven and a take-up roll located above the cloth roll and having a journal at each end comprising bearing brackets fitting against the under surface of the breast beam and secured to the frame above and at the ends of the cloth roll to receive the takeup journal, each of said bearing brackets presenting a cylindrical bore fitting the journal and having in its upper surface a shallow recess into which the oil is fed through the oil opening in the breast beam and a port leading from said recess through the top of the bearing to deliver oil upon the journal at a distance remote from the end of the journal which is adjacent the take-up roll, an annular recess concentric with and opening throughout into the bore near the end thereof adjacent the take-up roll, and a drainage channel extending at the bottom of the bore from the annular recess to the opposite end of the bore, whereby lubricant supplied to the take-up roll bearings is pre vented from creeping along the take-up roll journals and over the take-up roll ends or whence it can reach the cloth passing around the take-up roll or drop upon the cloth roll or the cloth, and is caught by the annular recess and led through the drainage channel to an innocuous position.

In testimony whereof, I have signed my name to this specification.
